Re: Re-compiling PHP changes server responsiveness

Running ok as test server, but unusual error from added, complex CMS

Now server does not respond, either to 'localhost' request on its 
browser, or specific address request from another machine on local network.


I assume re-compiling PHP would not clobber hosts or resolv.conf (they 
look ok).


I get: "[warn] (2)No such file or directory: Failed to enable the

/var/log/httpd-error.log" four times


Tried adding accf_http="YES" to /boot/loader.conf, and re-booting of 
course.


This is just a warning message and doesn't stop apache working or not.  Enabling
accf_http should give you a bit of a performance boost under heavy load and help
you withstand certain types of DoS attack, but it's not required.

Tried refreshing ports (inital re-compile attempt failed with make 
complaining that postgres-client had been marked invalid - when will 
someone fixit?), and re-compiling apache22 => no change.


ps -auxc: no httpd.

FF3 under Gnome on the machine fetches external pages, of course (using 
router DNS).


What else should I look at?



Try restarting httpd from the command line: /usr/local/etc/rc.d/apache22 restart

This will run a configtest and then try and start up apache.  Then check
that apache is still running: /usr/local/etc/rc.d/apache22 status

If apache has mysteriously disappeared and there are no messages in log files,
then it means apache crashed during the startup process soon after daemonising.
That's pretty diagnostic for loading a dynamic module that disagrees with it.

At a guess, and given that you've reinstalled all your php modules, I think you
may be being hit by the php module load order problem.  In that case, running
php from the command line will probably also segv on you.  This is something 
that
has had quite a lot of attention on this list, but there isn't a really good 
solution
yet, other than manually reordering the entries in 
/usr/local/etc/php/extensions.ini

Also, if you're running eAccelerator, make sure you recompile it at the same 
time
you upgrade the main lang/php5 port: eAccelerator will cause Apache to crash if 
you
try and run it against a different version of PHP than it was originally 
compiled
for.

Cheers,

You've probably already spotted this, but this behaviour is documented in 
largeinstallationtweaks.html:

``Normally Nagios will fork() twice when it executes host and service checks. 
This is done to (1) ensure a high level of resistance against plugins that go 
awry and segfault and (2) make the OS deal with cleaning up the grandchild 
process once it exits. The extra fork() is not really necessary, so it is 
skipped when you enable this option. As a result, Nagios will itself clean up 
child processes that exit (instead of leaving that job to the OS). This 
feature should result in significant load savings on your Nagios 
installation.''

It can also be enabled separately in nagios's main config file - 
child_processes_fork_twice is the option to look for.

Emil-

Thanks for your response... I don't know that that's quite right.
SUIDDIR has to be enabled in the kernel as an option to enable the
functionality on UFS and my tests on ZFS haven't proved fruitful:

$ sudo zfs create zroot/shared
$ sudo zfs umount zroot/shared
$ sudo zfs mount -o suiddir zroot/shared
$ sudo chown sats:office /zroot/shared
$ sudo chmod 4770 /zroot/shared
$ touch /zroot/shared/file
$ ls -al /zroot/shared/
total 4
drwsrwx---  2 sats  office  3 Dec 16 23:26 ./
drwxr-xr-x  4 root  wheel   9 Dec 16 23:26 ../
-rw-r--r--  1 ben   office  0 Dec 16 23:26 file

With a drive mounted with the 'suiddir' option (and the kernel option
enabled) the above works with UFS. I was curious if maybe there was an
option in 'zfs set' that I was missing.

Any clues would be appreciated.

FreeBSD's slice is a "DOS primary partition".
FreeBSD's partition is comparable (but not equal to) a "logical
volume inside a DOS extended partition".

The limitation to 4 slices is due to DOS limitations that 
are still present for legacy in the PC sector.

Yes.

No. As far as I understood and listed before, a "DOS primary
partition" cannot be subdivided. That's why the "DOS extended
partition" has been "invented" which allows subdivion by the
means of "logical volumes". A "DOS extended partition" takes
the place of a "DOS primary partition".

I've not had problems accessing them so far.

But only the subdivisions of a FreeBSD slice are called this
way.

But not all at the same time. :-)

Yes.

No. The MBR usually branches to the first slice it finds that
has the bootable flag set. It doesn't have to be the first
one on the disk.

In case of FreeBSD, feel free to read "man boot" which gives
a good introduction to the topic.

Exact.

I was always a fan of Wireshark (ex Etherial). It's lightweight

There are gv (which is limited in some way, "fancy" PDF files)
and xpdf.

I can recommend "xpdf -fullscreen " especially for use
in presentations.

In both programs, keyboard support (important for comfortably
browsing a document) is good.

Of course, KDE and Gnome provide their own PDF viewers, but
since you don't want to use the Linux ABI just for a PDF
viewer program, you surely won't want to install KDE or
Gnome just for the same purpose. :-)

But I have to tell you that for some very special PDF files,
especially those that use nonstandard stuff, and for those
that "process" input fields, the acroread port is still
on my system as "fallback solution".

Paths.  When there's a problem with cron it's (almost) always paths. 
portsclean is a ruby script that starts with this line:


#!/usr/bin/env ruby

That should find and run ruby.  Your /etc/crontab should have these lines:

SHELL=/bin/sh
PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin


And now that I tried a test with these manual paths, the same thing 
happens:


# setenv PATH /etc:/bin:/sbin:/usr/bin:/usr/sbin
# env ruby
env: ruby: No such file or directory

Doh.  ruby and ruby18 are in /usr/local/bin.

So it's working as designed.  A reasonable way to fix this is to add 
:/usr/local/bin to the crontab path, but that may not be the right way 
to fix it.

I don't know if it's of any help, but I had a *somewhat* similar experience, I
don't know if this will help, but I'll give it to you for what it's worth: I
found in my environment, I had REINPLACE_CMD defined (seemed to be a good
value), so (in my shell, tcsh) I removed the REINPLACE_CMD setting with
unsetenv, and the problem disappeared.  Use either env or printenv to scan your
environment for anything to do with sed (as REINP"LACE_CMD does) and try
removing it.

Oh, BTW, I can't seem to get the -l  option to portupgrade to work, any
help on that would also be appreciated.  I didn't use -L at all.

Interestingly, my homemade port rebuild script is recently broken with

low-level "for i in `cat list`" type script which recently has begun

Many thanks. I have had -e work many times


But -e does not mean what you think here:

-E  Interpret regular expressions as extended (modern) regular
expressions rather than basic regular expressions (BREs).  The
re_format(7) manual page fully describes both formats.

-e command
Append the editing commands specified by the command argument to
the list of commands.

So sed -E means "interpret regular expressions as extended" and -e is 
followed by a command:


sed -E -e 's/a/b/' -e 's/x/y/'


if you call sed from either the command line or a shell script as in

sed -f somefile

with somefile being 1 or more lines of sed commands. When the
file itself is the script, the first line actually calls sed
from within the file.


I'm not clear on why you want to do it that way instead of simply 
calling sed from a shell script, but sed -Ef seems to do what you want.

portupgrade failure

Hello all,

I've been having this problem for a couple of months now, but I just
recently decided to try to fix it. I'm running FreeBSD 6.4, and if I
try to use portupgrade to upgrade something, I get an error (seems to
be the same for other ports):

Sun Grid Engine: occasional job submission errors

[Joey Mingrone]

We are using Freebsd 8.0 / sge-6.2.2.1_1on a computing cluster
(http://awarnach.mathstat.dal.ca/).  It's been working well, however
we see the error below when a lot of jobs are submitted in a short
time (e.g. in a loop on the command line) using
"qsub".

error: commlib error: can't connect to service (Address already in
use) Unable to run job: failed sending gdi request. Exiting.

Has anyone seen this problem before and found a solution?

Cheers,

Joey Mingrone

Re: sed -f Script Syntax

[Martin McCormick]

Warren Block writes:

Many thanks. I have had -e work many times if you call
sed from either the command line or a shell script as in

sed -f somefile

with somefile being 1 or more lines of sed commands. When the
file itself is the script, the first line actually calls sed
from within the file. I was just wondering if the sed used in
freeBSD had a way to let one put the -e flag in there also. -ef
or -fe doesn't cut it:

sed: 1: "f
": invalid command code f

That was with sed -ef. If you try sed -fe, it bombs with the
same complaint only now it doesn't understand the e so there can
apparently be only one flag after the -.
#! /usr/bin/sed -f -e doesn't work either.

Someone wrote me off list chiding me that this is not a
freebsd question. Well, I am running this under freebsd and
there are sometimes slight differences between bsd-style
commands and other flavors of Unix such as Linux. They are not
numerous, but try date -r1234567890 under freebsd. You get:

Fri Feb 13 17:31:30 CST 2009

Try that same command under Linux:

date: 1234567890: No such file or directory

That date command wants the string in a file to produce similar
results.

ping -o under freebsd is incredibly useful when you want
to know when an interface comes up. Under Linux and earlier
versions of FreeBSD, it does nothing but tell you it didn't
understand -o. Again, thank you for answering.

Transfer zfs pool to new hardware

[mailinglists]

All,

My machine had a failing motherboard so it was decided to put the drives
of the failed machine in a different machine to be able to continue
service.

The old server had 2 drives in a mirror setup (gmirror) and these were
recovered fine in the new server, these disks contain the OS so everything
is up and running again.

In addition to the mirrored drives there was a zfs (raidz) volume to
contain bulk data, this pool was built using 4 750G drives (all the same
disks) but this hasn't come up properly. I'm not sure if the disks were put
in the server in the same order and the device naming in the new machine
has changed also. One thing that stands out (for me) is that the /dev/ad12
comes up twice in the 'zpool status' output (see below), I'm not sure if
this is expected..

Old situation:
zfs raidz containing /dev/ad10, /dev/ad12, /dev/ad14 and /dev/ad16
(working fine)

In the new machine /dev/ad16 doesn't exist and the drives are numbered
different:
/dev/ad8, /dev/ad10, /dev/ad12 and /dev/ad14


My question is; can the data on this zfs pool be recovered?

Some more detailed information is below, but I'd be happy to provide
additional information if needed.

Can display be shared through VNC using xorg vnc module?

[Yuri]

I read here: http://en.gentoo-wiki.com/wiki/X11VNC that in Gentoo xorg 
can load "vnc" module and it will make it also a vnc server.

But I can't find any relevant ports in FreeBSD port tree.
I only found net/x11vnc which is a standalone program that connects to 
xorg server and serves as it's vnc server.


Does this meant that "vnc" module isn't supported on FreeBSD? Or it was 
replaced by x11vnc?

Great, the list is back!

Okay, well, very-soon, I'll need to plug in my watt-meter to
see how much juice my server, firewall, and maybe one desktop
take.  Guessing is less than 500w.  Is there a tutorial for
newbie on how to use this beast?

Optimally, I would like the UPS to run for a few minutes, then
instruct that things be "shutdown -h 120" (say).  That is easy
to write; difficult to program.

thanks,

gary

Not expected, exactly, but not surprising.  The hardware should be fine.


I have been having issues with VirtualBox where doing IO (network and HDD)

That sounds like a separate problem.

Can someone please show me how?


Okay, but realize this is a potentially dangerous operation.  Read the 
man page for patch(1) and the Handbook section on kernel configuration. 
Also, that patch is from a user and may not be of the same quality as if 
it were officially part of the FreeBSD source tree.


That said, download the patch.  It's called patch1.diff.

The first three lines show which file will be patched: 
sys/dev/bge/if_bgereg.h


On a normal FreeBSD system, system source file paths are relative to 
/usr/src.  So, as root:


cd /usr/src
patch < patch1.diff

You should see messages about patch hunks succeeding.  If there were no 
errors, you can build from the now-patched source.  This patch is to an 
Ethernet driver, so you probably only need to rebuild the kernel.  See 
the Handbook for custom kernel building and installing:


http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html

If you don't have a custom kernel, you don't need the KERNCONF= entries, 
or can use KERNCONF=GENERIC.


Finally, reboot and hope it works.

At this point I thought I would try Xorg 7.4. I did a "pkg_delete -a" and

How, specifically?


The keyboard was locked only the power key worked. As in my earlier response I 
tried as many variation of the option as indicated by the handbook and my 
imagination. It is probably true that xorg worked albeit without the keyboard.
Neither startx or xdm acted differently. E.g, I got a black screen and a locked 
system.


After trying all the configuration options, tips etc in the handbook, 
google et all, I decided my 3+ year old thinkpad was just not supported so 
I composed a "can anyone help me" email to questions. This went off into 
the ether through user error.


While I was waiting for help I thought I would try installing Xorg from an 
iso image. The resulting install worked out of the box using the last 
variation of xorf.conf I had tried. I am left to assume that what I got 
from pkg_add does not fit together.


The symptoms described in your earlier mail sound like it worked but was 
different from what you expected.


I do not think so because after installing from the iso, startx and xdm worked 
with the last version of my xorg.conf file.


Obviously my earlier attempts to get an xorg.conf file worked fine. The 
code did not. As a thought to the Xorg, I do not think the unbundling makes 
things more stable. Xfree86 was bad enough (so I thought) with its couple 
of dozen (or so) components. Starting from scratch I now have 204 ports and 
two versions of python just to run twm. Given that some number of the 204 
component are under active development using pkg_add seems out of the 
question. The second version of python came in because I could not find xdm 
in the 7.2-release disk1 iso so I did a pkg_add on xdm.


This sounds like you are mixing old and new packages.  portupgrade (and 
probably also portmaster) can use packages for you.


Maybe. But if I start with a system with no ports and do a pkg_add, I do not see 
how I am mixing old and new. This was certainly true before I deleted everything 
but I was trying only to upgrade firefox2 --> firefox3 on xorg 7.3 using 
portmaster and then portupgrade. When that did not work (and I have no issues 
with that) I delete all ports and started with xorg 7.4. I see no other 
conclusion other than one (or more) of the 204 ports installed by pkg_add was 
too old (or new).

Each drive has a sector 0.   When you install FreeBSD you can write
an MBR in to that sector 0.   You can also install other (third party)
MBRs in to that sector.

The sector isn't the MBR.   The code and table that gets written to
that sector is the MBR.If you don't want to boot from the drive - 
eg just use it for data, you can ignore that sector and not write any
MBR in to it.

The MBR has a little table in which is marked which slice to
continue the boot with.   The FreeBSD MBR (and some others) sets
that to be the current slice when a boot is done.   So, the last
slice to be booted is always the default boot the next time.  You
can manually change that with fdisk(8).

Some people have wanted to have a fancier MBR than can fit in a
single sector.   Almost all systems nowdays use that 0 sector, but
then just ignore the rest of the track that it is in.  So, there are
several "wasted" sectors following the MBR.   Those people have made
use of that space to install a more elaborate MBR, depending on 
that extra space never being used for anything else - which is a pretty
good bet.  In fact, I don't quite understand why people don't just
go ahead and define the standard so that track is specified as available
for MBR.

The MBR is fairly basic and conforms to a fairly tight but primative
system for finding and initiating boot sectors in slices/primary
partitions.Because that part is almost all the same across most
systems, most MBRs can boot most OSen on PCs if they want to.  MS does
not seem to want to, but FreeBSD and Linux can.

But, the boot sector in each slice/primary partition is unique to
the OS being booted.   It has a common boot flag setup and a common place
to jump to to begin execution, but the rest is OS specific.

Basically, the BIOS does its thing and looks for an MBR in sector 0 of
the drives in its boot list.   The first one it finds, it loads in
and transfers control to it.   The MBR does a couple checks and looks
for a bootable slice and which is flagged to be the default boot.  It
puts up a simple boot menu allowing you to choose.  If you do not 
respond in time, it goes with the flag setting.  

The MBR then reads in the first (boot) sector of the slice and transfers
control to it.   That sector code knows how to find what it needs to
finish the boot, load the kernel, etc and start up init which gets
everything else going.   

The process has changed in detail, but not much in concept since the
beginning of computer OSen.  The reaason it is called booting is that
especially in the old days, when some parts of the startup were keyed
in by hand, it had the feeling of the system pulling itself up by
its own bootstraps - an old an

Xorg defaults to a black screen instead of a checkerboard pattern these days.
Keyboard and mouse input is handled by hald(8), so don't forget to enable and
start it before starting Xorg. hald depends on dbus so that also needs to be
enabled and started. Add the following to rc.conf:
hald_enable="YES"
dbus_enable="YES"

Good luck,

Thanks for your reply. I tried all that and more. Installing xorg 7.4 from the 
7.2-release iso worked with the last verision of my xorg.conf file which 
happened to be not using hal and dbus.

is this booting info correct?

[Fbsd1]

Users with Microsoft/Windows knowledge of how a hard drive is configured
may have a terminology issue with FreeBSD. Microsoft/Windows and FreeBSD
use the word partition to mean different (but related) things.

FreeBSD and Microsoft/Windows have primary-partitions, but they call
them different things. FreeBSD calls the Microsoft/Windows
primary-partition a slice.

The number of hard drive primary-partitions/slices is determined by the
motherboard BIOS (Basic input output system), not the operating system.
Standard motherboard BIOS limits hard-drives to 4 main divisions

Each of those are called primary-partitions in Microsoft/Windows
terminology and slices in FreeBSD terminology.

Each primary-partition/slice can be sub-divided into smaller chunks. In
Microsoft/Windows, they are called extended-partitions. They are
implemented very differently and are not compatible with FreeBSD. In
FreeBSD the sub-divisions are called partitions.

Each one of the 4 max primary-partitions/slices can be made bootable.
The first physical track of the allocated space of each
primary-partition/slice has an initial sector (512 byte block) that is
called the boot sector. If it contains boot up code the motherboard BIOS
considers it to be bootable.

Each physical hard drive in the PC has it's own MBR (Master Boot
Record). The MBR is located in sector-0 of the first physical track on
the hard drive. The standard MBR in Microsoft/Windows and FreeBSD
defaults to booting the first primary-partition/slice allocated on the
first hard drive cabled to the PC.

There are MBR booting programs that you can load into the MBR on the
first physical cabled hard drive to scan for other bootable
primary-partitions/slices on this hard drive and any other hard drives
cabled to the PC. It displays a menu giving you the option to choose
which one you want to boot from. This gives you the ability to have more
that one operating system installed on your PC at one time.

Device not configured

[David Naylor]

Hi,

I booted into single user mode (running FreeBSD 8 RC2) and did:

# dd if=/dev/ad8 of=/dev/ad8 bs=1024k

After waiting a few hours the command completed without problem (ad8 is the 
HDD that has FreeBSD).  After that I got the following:

# reboot
reboot: device not configured
# ls
vnode_pager_getpages: I/O read error
ls: device not configured

Pressing the boxes power button results in the above vnode message to spam the 
screen.  The only way to reset the system was to do a hard reset (root was ro 
:-) ).  

Is this expected behaviour or something wrong with the HDD?  

I have been having issues with VirtualBox where doing IO (network and HDD) 
causes DMA problems resulting in the system panicing and rebooting.  Could 
this be related?  

I haven't finished diagnosing the VirtualBox problem but booting the guest in 
safe mode (the guest is FreeBSD-current) does not fix the problem.  

Thanks for your assistance.

David

Can I rescan for new PCI devices? Or should hotplugging Expresscards work?

[Bob Johnson]

I'm using an ExpressCard for wireless networking because there seems
to be no driver for the internal card in my laptop (and NDIS panics
the system). The Expresscard shows up as a PCI device and works fine,
except that it must be in the system at boot time to be recognized.

Judging by old posts I found on the topic, it appears that automated
hotplugging of PCI devices is probably still work in progress, but is
there a way to manually have the system rescan for PCI devices so I
don't have to reboot when I insert the network card?

I'm using 8.0 RELEASE amd64.

Thanks!

sed -f Script Syntax

[Martin McCormick]

If you have a sed script that is executable as in the first line
starts with
#! /usr/bin/sed -f
and the following lines are like:

/this repetitive line/d
/and another repetitive line to go/d

This all works great. You just make the file executable and use
it as a filter if you want to remove any instance of those lines
in text.

How does one embed a command in this filter to make sed
understand an extended or modern regular expression like:

/part 1[[:space:]]text\/html[[:space:]]/d

This is normally the -e flag but I haven't figured out how to
put it in the script. I would like to either use it to make that
one line show up as an extended regular expression or make sed
run the entire script in the -e mode.

In this particular case, I have made a 14-line script
called nuisancefilter that vaporizes annoying blocks of text
from  Email messages.

I have read the man page and it says that this is
possible, but I never quite understood how to apply the commands
to an executable sed script file.  Many thanks.

question about xorg 7.4

[doug]

I have a IBM thinkpad T42p. xorg 7.4 is pretty much a disaster for me. First I 
wonder if anyone has gotten 7.4 to work on this or similar hardware. The system 
is 3+ years old when it was still IBM.


I have done this a time or two starting with the first version of KDE and 
FreeBSD 4.. I believe I have tried all of the options in the handbook 
plus a couple of various from this list and google. So I was not going to add 
xdm and Xorg output, at first anyway.


The one thing I have not done is upgrade the BIOS and am not sure that matters. 
I was/am afraid of breaking an otherwise great system. It runs xorg 7.3 and 
KDE 3 or 4 fine. I go to this point because I broke things trying to install 
firefox3 and got all tangled up in upgrading ports and thought I would give xorg 
7.4 a try.


I am running FreeBSD 7.2. Xorg was installed using pkg_add on a system without 
any ports. Upon hitting the xdm trap, I also installed that package.


All variations give me a black screen with the keyboard locked. startx, xdm and 
xorg all do the same. I assume this is a hardware issue and hope someone found a 
way around it.


Thank you for any thoughts, tips, ideas, etc.

ipfilter unwanted blocking

[Oleksii Krykun]

Hi,

I use FreeBSD 7.2-RELEASE with IPFilter used as proxy server for our LAN.
I have following rules for external interface:

block in log on rl0 all head 100
block out log on rl0 all head 200

pass out quick proto udp from a.b.c.d/32 to any keep state group 200
pass out quick proto tcp from a.b.c.d/32 to any  flags S/SA keep state keep
frags group 200

All works but sometimes IPF block all (or most of them) packets to ports 80
and 53 for about 2-3 up to 40-50 s.
After this IPF returns to normal operation.

How to investigate this problem? I tried remove flags and "keep frags" but
without success.
No regularity.

Is this a IPF problem, wrong packages or kernel settings? Any idea?

USBserial port convertor

[stan]

I need to support 5 RS-232 streams with my FreeBSD 7.2 machine. I just
purchased UTS-408A-S1 8 port adapter. When I plug it in, I get the
following in dmesg:

uhub3:  on
uhub1
uhub3: single transaction translator
uhub3: 4 ports with 4 removable, self powered
ucom0:  on uhub3
ucom1:  on uhub3

Do I need to add a driver to my kernel? Right now I have the GENERIC one
installed. What devices should I try?

Up grading ports, Xorg et all

[doug]

I messed up a KDE 3.5.10 trying to install firefox3 so I thought I would attempt 
to upgrade using portupgrade and/or portmaster. After a lot of work I think I am 
back to if you use KDE the only way to upgrade is to start afresh.


At this point I thought I would try Xorg 7.4. I did a "pkg_delete -a" and 
"pkg_add -r xorg". This was a complete disaster. After trying all the 
configuration options, tips etc in the handbook, google et all, I decided my 3+ 
year old thinkpad was just not supported so I composed a "can anyone help me" 
email to questions. This went off into the ether through user error.


While I was waiting for help I thought I would try installing Xorg from an iso 
image. The resulting install worked out of the box using the last variation of 
xorf.conf I had tried. I am left to assume that what I got from pkg_add does not 
fit together. Obviously my earlier attempts to get an xorg.conf file worked 
fine. The code did not. As a thought to the Xorg, I do not think the unbundling 
makes things more stable. Xfree86 was bad enough (so I thought) with its couple 
of dozen (or so) components. Starting from scratch I now have 204 ports and two 
versions of python just to run twm. Given that some number of the 204 component 
are under active development using pkg_add seems out of the question. The second 
version of python came in because I could not find xdm in the 7.2-release disk1 
iso so I did a pkg_add on xdm.


Aside from venting a bit, my message is the Xorg set from a release iso probably 
has a better chance of working if you run into problems. I do not own or have 
access to any systems that could build Xorg or KDE in less than a month so I 
am clueless if building from source would have worked any better.

Why VNC server crashes when client disconnects?

[Yuri]

I used vnc while ago without this problem.
Now I see that when client gracefully exits (window close) server 
crashes with exception:

terminate called after throwing an instance of 'rdr::EndOfStream'
knotify: Fatal IO error: client killed
kwin: Fatal IO error: client killed
ksmserver: Fatal IO error: client killed
kaccess: Fatal IO error: client killed



Is this something temporary, or somethig's wrong with my system?

Re-compiling PHP changes server responsiveness

[Ian Fitzgerald]

Recently upgraded (fresh install) FBSD 8, including MySql, Apache22, 
phpMyAdmin, KDE4 Gnome2.26 from DVD iso.
Running ok as test server, but unusual error from added, complex CMS 
prompted me to re-install PHP5 and PHP5-extensions as pkg_add -r (using 
ports files from iso), then with no success, compiling them (using ports 
files from iso), with slightly different make config.


Now server does not respond, either to 'localhost' request on its 
browser, or specific address request from another machine on local network.


I assume re-compiling PHP would not clobber hosts or resolv.conf (they 
look ok).


I get: "[warn] (2)No such file or directory: Failed to enable the 
'httpready' Accept Filter, and no new errors in 
/var/log/httpd-error.log" four times


Tried adding accf_http="YES" to /boot/loader.conf, and re-booting of course.

Tried refreshing ports (inital re-compile attempt failed with make 
complaining that postgres-client had been marked invalid - when will 
someone fixit?), and re-compiling apache22 => no change.


ps -auxc: no httpd.

FF3 under Gnome on the machine fetches external pages, of course (using 
router DNS).


What else should I look at?

Native PDF viewer

[Rolf Nielsen]

Hi all,

Since I don't have Linux compat layer activated, and I have no need for 
it, I'd like to ask if anyone can suggest a native PDF viewer (I'm not 
fond of the idea of installing a compat layer for just one application). 
Currently I'm using GIMP to view PDF files, but since GIMP opens them 
either as several single pictures (one per page) or one picture with 
several layers (one layer per page), it gets a little hard to browse 
through the pages, especially with big documents, e.g. my camera manual.


I founed several apps among the ports, too many to test them all, so if 
anyone has ideas or can tell me what the pros and cons are for some of 
those apps, I'd greatly appreciate it.


Cheers,

Rolf Nielsen

Problem with snd_hda and Realtek ALC260 and FreeBSD 8.0

[Felix Janssen]

Hi,

I have a Sony Vaio laptop which has a HDA sound card. The sound used to 
work fine with FreeBSD 6.4. I recently upgraded to FreeBSD 8.0 and I 
can't get the sound to work. Below are dmesg, sndstat and pindump 
outputs. Even the beep which sounds when you press esc in a terminal 
does not work.


What could be the problem and how can I fix it?

Kind regards,

Re: 8.0: OpenSSL stat()'s NLS 500+ times causing extreme system load

I tried that and as you predicted, all the bogus stat calls went away.

Unfortunately the performance issue did not. :(  Back to the drawing
board for me!

Upon further inspection, it seems as though for each check, Nagios
spawns a process that spawns a process that spawns a process that runs
the check.  I did "ktrace -i -t w -p (nagiospid)" on Nagios for 30
seconds and the ktrace output contained records from 2365 different
processes spawned in that 30 seconds.  During that time, I would
expect about 800 checks to have run, so it does seem like it's right
at 3 processes per check.

I just don't think the system can keep up with all that fork()ing
without going all out; it's just a limit of the Nagios plugin
architecture.

But thank you very much for point me in the right direction!
